Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 135135 to 190190 cm and weights of 3838 to 150150 kg. The 100 paired measurements yield a mean height of 167.56167.56 cm, a mean weight of 81.3881.38 kg, requals=0.1870.187, and ModifyingAbove y with caretyequals=negative 106−106plus+1.071.07x. Find the best predicted weight given an adult male who is 176176 cm tall. Use a 0.050.05 significance level.

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?

While scuba diving, rajeev dove to a depth of 12.6 feet below the surface of the water and then descended another 8.7 feet. what expression can be used to find rajeev's new position? 12.6 – 8.7 –12.6 – 8.7 –12.6 – (–8.7) 12.6 – (–8.7)

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
